When the Charlie Card was originally introduced, they were talking about the fact that unused tokens that were out-and-about in circulation (and lost, in token collections, rolled under someone's dresser, etc.) with low likelihood of ever being used presented some accounting difficulties, and that making unused fares expire after six months was an accounting win, and that was why fare cards were a win for the T financially.
